Amprobe R-277 & R-277S REMCON Relays are solid-state relays designed to replace electromechanical relays in various applications. They offer several advantages over traditional relays, including:

1. Solid-state switching: The R-277 & R-277S relays use solid-state switching technology, which eliminates the need for mechanical contacts. This results in longer life, faster switching speeds, and reduced maintenance.

2. Higher current capacity: The R-277S relay has a maximum AC current rating of 6.5 Amps, which is higher than the 5 Amps maximum rating of the R-277 relay. This makes the R-277S relay suitable for applications with higher current requirements.
